2 Claims.

This invention relates to new and useful improvements in holders such asare employed for holding electrodes during welding operations.

The principal object of the present invention is to provide a holderadapted to hold electrodes at various angles to meet the convenience ofthe welder.

Another important object of the invention is to provide an electrodeholder which is completely insulated for the purpose of safeguarding thewelder from electric shocks, and protect all metal parts of holder fromsparks, flash and spatter caused by electrode while in operation.

Other objects and advantages of the invention will become apparent tothe reader of the following description.

In the drawings Figure 1 is a side elevational View of the implement.

Figure 2 is an end elevation looking at the forward end thereof.

Figure 3 is a top plan view.

Figure 4 is a longitudinal sectional view taken on the line 4-4 ofFigure 3.

Figure 5 is a longitudinal sectional view taken on the line 55 of Figure1.

Figure 6 is a cross-sectional view taken on the line 6-5 of Figure 4.

Figure 7 is an end elevational view of the stationary jaw.

Figure 8 is a fragmetary side elevational viewmodification of thestationary jaw.

Figure 10 is a fragmentary side elevational view showing the modifiedstationary jaw.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that the holder is made up of an elongated barrel 5 having aslot 6 at one end thereof for receiving the cam head I of a hand lever Bwhich is fulcrumed within the barrel 5 on a pin 9. The cam I has aforwardly projecting jaw III which is cooperative with a jaw piece llsecured to a projecting portion I2 of the barrel 5.

Numeral l3 denotes a screw for holding the jaw piece I I to the portion12 and as can be seen in Figure 5, the jaw piece II has crossed groovesl4, 45, a transverse groove l6 and a longitudinally extending groove ll,these grooves intending to receive welding rods positioned at variousangles.

The barrel 5 has a tubular extension [8 open at its forward end as at Hto permit the insertion of one end of a welding rod. The tube 18 is ofinsulation material and has a metal annulus 20 at its forward end toprotect the same against the flame during welding operations.

A clevis 2| is pivotally secured to the cam l and with this hooks oneend of a tension spring 22 which extends rearwardly in the barrel 5 andhooks over a cross pin 23 in the barrel. The usual welding current linewhich in Figure 4 is denoted by reference character A can be secured inplace by set screws 24.

An elongated tubular hand grip 25 of suitable insulation is secured tothe barrel 5 by a screw or other means 26 and this hand grip 25 extendswell rearwardly of the barrel -5 to enclose a portion of the insulationof the supply line A.

If desired, the stationary jaw may be constructed as shown in Figures 7and 8 wherein the projection in of the barrel 5a has a recess 21 forreceiving a boss 28 depending from a jaw piece I la and a set screw I3ais disposed upwardly through the projection Ma and threadedly disposedinto the boss 28.

A second modification of the stationary jaw is shown in Figures 9 and10. The jaw is denoted b the reference character I l b and has adovetail groove therein to permit the jaw to be disposed over adovetailed-shaped extension I21) on the barrel 5b.

It can now be seen, that by depressing the hand lever 8, the jaw I0 islifted and a Welding rod can be inserted through the side opening 30 orthrough the front opening l9 and due to the varied dispositions of thegrooves in the jaw piece, the welding rod can be set and held in anydesired position. The rod is held by the releasement of the hand grip 8so that the spring 22 rotate the cam I and forces the jaw l0 against theinner end of the welding rod.

The cam I, 'hand lever 8 and forwardly projecting jaw ID are of onepiece of non-metallic material.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. A welding rod holder comprising an elongated tube, a sleeve ofinsulation on the tube defining a hand grip, a tubular extension on thetube having a slot therein, a hand lever fulcrumed in the tube extensionand projecting through said slot, a jaw carried by the hand said slot, ajaw carried by the hand lever within and enclosed by said extension, afixed jaw with diagonal grooves within said extension and enclosedthereby, said tubular extension being provided with a protective shieldat the forward end thereof and having a, front and opposed side openingsextending through the same and through said protective shield forselective use in inserting a welding rod into the extension into 10alignment with said grooves.
